This way it can be reused by other platforms if needed. Note that this driver is designed to work with the Versatile Express NOR flash of Juno and FVP. In said platforms, the memory is organized as an interleaved memory of two chips with a 16 bit word. Any platform that wishes to reuse it with a different configuration will need to modify the driver so that it is more generic.
